Wake requests could block beyond the join budget, report success while another request was still failing, and stall UDP receives. HostPort sleep/wake could also create the replacement listener before the previous pod released its port or move it away from the advertised node.

Bound the shared wake PATCH and total join attempt, propagate its actual result to concurrent callers, and coalesce UDP wake work behind a bounded queue. Persist the HostPort endpoint node and UID, wait for actual pod drain in both directions, and pin the game and sentinel through scheduler affinity. Missing or unschedulable endpoint nodes report an explicit condition.

Closes #729. Closes #730.

Validation:

• Linux operator/sentinel production builds and operator envtest, sentinel, and E2E test-source compilation passed. Tests were not executed locally, per repository policy.
• Added real TCP/UDP regressions and a dedicated two-node CI bucket for repeated handoffs, occupied ports, terminating sentinels, cordoned nodes, and node deletion.
• Actionlint and offline zizmor passed. Independent review completed.

Resource requests remain in the separate #724 change. This PR shares reconciliation code with #760; integration must retain its operation fence and these HostPort handoff gates. Existing web/Compose image builds on this base also need the unrelated template-picker fix in #759.
